Aston Martin One-77 2010 Owner's Manual page 29

If HomeLink now does not operate the garage door
opener (or other device), this may be because the
original remote control has a rolling code feature
(Refer to 'Rolling Code Synchronisation', page
2.17)
.
Rolling Code Synchronisation
Check, by going through the following steps, whether
or not the garage door opener (or other device) is
equipped with a rolling code feature.
• Look in the garage door opener manual for
clarification
• The remote control apparently programs HomeLink
but HomeLink does not operate the garage door
opener
• Press and hold down the programmed HomeLink
button.
With a rolling code system, the HomeLink LED
flashes quickly for a short time and then stays
ON constantly for two seconds. This pattern
repeats itself for up to 20 seconds
If HomeLink was programmed with a rolling code
system, then after the end of the programming period
it must be synchronised with this system again before it
will function correctly.
Follow the instructions below for Rolling Code
Synchronisation (the procedure will take less time with
a second person to help).
The vehicle must be within operating range of the
garage door opener and the ignition set to ON. Make
sure you comply with the safety instructions even when
synchronising the rolling code.
1. Locate the Training button (programming
button) on the garage door opener motor
head unit. Exact location and colour of the
button may vary by gate or garage door
opener brand (refer to the operating
instructions of the garage door opener
'Training additional remote controls').
2. Press the Training button (programming
button) on the garage door opener motor
head unit (which will usually set a 'training'
LED to ON).
Following step 2, there are typically 30
seconds in which to initiate step 3.
